POT = power of two texture
NPOT = non power of two texture
He certainly use rectangular textures for a gui

So all is said : It is up to you to find another way ....
This is why I talked about "manually" doing it

@ Daytona675x
Excuse me but "Tu te noye dans un verre d'eau"
Doing it manually is only
having/testing 2 flags : card_cant_do_npot uvarray->already_scaled

if(card_cant_do_npot)
if(!uvarray->already_scaled)
for each U V in uvarray
multiply U V with 2 floats resizeu resizev (no need for a full matrix)
